India’s farm waste turns profit: biochar and biogas drive new rural economy

India’s agricultural sector is tapping the value hidden in crop residues by processing them into biochar and biogas. The approach not only generates a marketable product but also offers a clean energy source for rural households. Farmers are increasingly partnering with private firms and cooperatives to set up small‑scale digesters and pyrolysis units, turning what was once a disposal problem into a revenue stream. Environmental benefits are evident as the practice reduces open‑field burning, cuts greenhouse‑gas emissions, and improves soil health through biochar application. Industry analysts see the trend as a catalyst for a new, sustainable rural economy that aligns with the country’s climate goals.
